[Cross antigenicity between human arterial tissue and various germs]

Cross antigenicity was demonstrated between human arterial tissue and enterobacteriaceae, some streptococcus strains or some viruses, using the indirect immunoenzymatic test. Absorption of antigerm antisera by the glycoproteins of either the human serum or aorta suggested that a glycoprotein or some fragment of it acted as a target-antigen or target-epitope for the investigated antibodies and that these antibodies might attack human arterial tissue.
